Nuclear Power Plant Air Intake Screen

Dec. 07, 2021

As an environmentally friendly energy source, nuclear energy is playing an increasingly important role in modern society. After years of development, my country's nuclear energy construction and production have continued to grow and develop. Nuclear power generation requires the extraction of large amounts of water from the ocean; therefore, water quality treatment is critical to the success of nuclear energy production. Seawater must undergo multiple chemical and physical treatments, including adsorption, precipitation or blocking to purify the water before it can be used in power plants. The blockage allows the water to pass through the filter material while excluding large chunks of impurities, thereby providing cleaner water for the power station. As a new type of structural filter material, wedge wire is increasingly used in nuclear power plants due to its excellent filtering accuracy.

Nuclear Power Plant Air Intake Screen

Work criteria

Inlet screens have formed a series of standardized products, which are widely used in petrochemical, food and other industries. These provide references for its promotion in nuclear power plants.

The application of the wedge-shaped wire water inlet filter in nuclear power plant facilities can filter the water in lakes, streams, rivers and reservoirs. The water inlet filter can be placed far from the coast to obtain better water quality and reduce the concentration and debris of marine life. When the pump draws water from the water, the water with impurities passes through the water inlet screen, pumping clean water into the pipeline, and filtering the debris and aquatic organisms out of the pipeline.

Comparison of different inlet filter materials

The most commonly used filter materials in nuclear power plants include woven metal screens, metal powder sintered screens, and laminated screens.

Structural strength, filtration accuracy, and pressure drop resistance meet all requirements

By looking at the above table, we found that the wedge-shaped wire intake filter has better performance and efficiency than other filter materials.

Although the application of air intake screens in nuclear power plants is still in a stage of rapid development, its unique structure and characteristics make it widely used in various nuclear power plant projects under construction.

Safety and reliability have been repeatedly verified in practice. Continuous improvement of the water inlet screen technology. With the continuous improvement of the wedge wire screen technology and the rapid development of nuclear power, the wedge wire intake screen will develop faster and more violently.
